Abstract
Description
- The invention relates to an exhaust gas turbocharger for an internal combustion engine according to the preamble of
claim 1. - EP 0 513 646 B1 discloses a method for the connection of parts consisting of steel and of an aluminum or titanium alloy, in which, in a first friction welding pass, a nickel lamina or a copper layer is applied to the steel part and a vanadium layer is applied to the titanium part. After the intermediate layers have been worked up mechanically, the parts are connected to one another in a second friction welding pass. The method is complicated because of the number of process steps and the material used for the intermediate layers.
- In a method for the friction welding of a steel shaft on a turbine rotor consisting of titanium aluminide according to EP 0 816 007 B1, a heat-resistant alloy is applied to the joining surface of the shaft before friction welding. Friction welding gives rise on the shaft to a cracked surface which is subsequently worked off.
- JP 08-281454 A shows the connection of parts consisting of titanium aluminide and of steel by friction welding, using an intermediate material having a low thermal volume change.
- In the connecting method according to JP 09-07609 A, a heat-resistant alloy having a central bore is applied by build-up welding to a steel part before friction welding to a part consisting of titanium aluminide. This is intended to avoid errors due to different thermal volume expansions.
- WO 92/20487 A1 describes a turbocharger, in which a hub connected to blades and consisting of an aluminum or titanium wrought alloy is friction-welded to a steel shaft, with a transitional layer which consists of a ductile secondary group metal being interposed. In a variant, a fastening component which receives radial sealing rings is used between the shaft and hub. The design is cost-intensive and requires a large amount of material.
- The object of the invention is to develop an exhaust gas turbocharger for an internal combustion engine, said exhaust gas turbocharger having a cost-effective construction and exhibiting improved functionality.
- The object is achieved by means of an exhaust gas turbocharger which has the features as claimed in
claim 1. Advantageous refinements may be gathered from the subclaims. - According to the invention, on a turbine wheel which consists of high-strength light metal alloys, in particular aluminides, a hub is formed which is connected to a steel shaft by welding. The aluminides are preferably a titanium aluminide or iron aluminide. The diameter of the hub is adapted to the diameter of the shaft at the welding point. The welding point is located, in the axial direction, in the vicinity of a bearing point of the shaft.
- Preferably, the shaft and the turbine wheel or the hub are connected to one another by friction welding directly, that is to say without the aid of intermediate pieces or intermediate layers. For mounting the turbine wheel or the shaft, two rolling bearings are provided which are spaced axially apart from one another, the weld seam lying between the bearings or on the side of the turbine wheel or on the side of a compressor wheel. The turbine wheel may be produced with a shaft extension by casting, a turbine-side shaft seal being integrated on the shaft extension. For receiving a shaft seal, grooves may be introduced into the extension or into the hub. The bearings may be formed on the shaft extension, the bearing inner rings or raceways being worked directly out of the material of the shaft extension. Furthermore, on the hub, cooling ribs, cooling blades or suchlike cooling elements may be formed, around which a cooling fluid flows in order to cool the shaft.
- In a preferred refinement of the invention, the rolling bearings are designed as hybrid or solid ceramic bearings.
- The invention affords a series of advantages. The exhaust gas turbocharger possesses low mass and therefore a low moment of inertia, so that the nonstationary behavior is improved. The exhaust gas turbocharger according to the invention has a high thermal and mechanical load-bearing capacity. This results, when an engine is in operation, in a higher possible engine power. On account of the heat-resistant material of the turbine wheel, the engine can operate at higher exhaust gas temperatures, so that the engine has lower pollutant emissions. The introduction of heat into the steel shaft or the mounting is only slight on account of the poor thermal conductivity of the material of the turbine wheel or of the hub or of a work-up shaft extension. In a turbine wheel consisting of titanium aluminide, owing to the high heat resistance and creep resistance, the blade geometry can be varied such that engine efficiency rises. In the connection of a turbine wheel and shaft by direct friction welding, outlay and costs are markedly reduced during the joining operation. If additional functional elements, such as sealing, bearing and cooling elements, are formed on the turbine wheel material having high load-bearing capacity, expenditure for additional parts can be saved.
